Hi All, Noel,
Ok that helped on the BB end, but when I imported the midi file into the single voice to a track program. Its import recognized that the guitar and the harmony track contained multi chs. But the BB Track still only had one guitar track number, same with the harmony track so am not sure that it split correctly on input.

I will have to open the midi file into other software as a test.

The mono synth will playback 16 chs, but each ch can only have single note lines.

Thanks
Happy Band In The Box
